ETSI TS 133 102 defines the security architecture, i.e., the security features and the security mechanisms, for the third
generation mobile telecommunication system.
A security feature is a service capability that meets one or several security requirements. The complete set of security
features address the security requirements as they are defined in "3G Security: Threats and Requirements"
(TS 21.133 [1]) and implement the security objectives and principles described in TS 33.120 [2]. A security mechanism
is an element that is used to realise a security feature. All security features and security mechanisms taken together form
the security architecture.
An example of a security feature is user data confidentiality. A security mechanism that may be used to implement that
feature is a stream cipher using a derived cipher key.
This specification defines 3G security procedures performed within 3G capable networks (R99+), i.e. intra-UMTS and
UMTS-GSM. As an example, UMTS authentication is applicable to UMTS radio access as well as GSM radio access
provided that the serving network node and the MS are UMTS capable. Interoperability with non-UMTS capable
networks (R98-) is also covered.
GSM security functions are defined in the TS 43.020 [36].
